Abstract

In order to improve a surgical instrumentarium for preparing a femur and a tibia for the implantation of the knee joint endoprosthesis, which instrumentarium comprises a first sawing template with three guidance slots for guiding a saw blade, which three guidance slots define three intersecting cutting planes, in such a way that the number of necessary instruments of the instrumentarium may be reduced, it is proposed that the instrumentarium comprises a second sawing template, that the second sawing template has a fourth guidance slot for guiding a saw blade, and that the first sawing template and the second sawing template are coupled to each other in a force- and / or form-fitting manner in a coupling position and are separated from each other in a separating position.
